UI
Inter-app audio
Background fetch
P2P (arguably, this isn't a new feature, it's essentially a wrapper to dns_sd)
Airdrop
Significant KitKat changes:
*Actual* SMS/MMS API
Storage access framework
Printing framework
Plus, Inter-app audio and Airdrop are essentially wrappers to P2P (which is also a wrapper to dns_sd), so the only real added feature was background fetch.
You could say the same about KitKat (except for SMS), so really it boils down to this:
iOS 7:

Background fetch
KitKat:
SMS/MSS API
Which Android still wins, IMO.
Plus, Android already has way more features than iOS already, not to mention the ability to install unsigned software, NFC, custom lockscreens/launchers and who knows what else.
Both are mature OS, ground breaking features are not expected. I'm not familiar with Android, but iOS tends to introduce new and improved API in each release that makes app development easier, there is lesser need to go down to core OS to develop your app. Beside what you mentioned, new in iOS 7: TextKit for fine typography control makes it easier to write text layout and editor; SpriteKit which is higher level framework for writing 2/2.5D games; game controller framework for standardise interface to game controller; 64-bit support; Open GL ES 3.
